Description

Technical Field

[0001] The utility model relates to the technical field of power devices, in particular to a novel adjustable power device. Background Art

[0002] The current market for adjustable power devices is primarily used in three-phase circuits. These products are bulky and cannot meet the needs of the growing intelligent and integrated world. The exponential increase in the number of electronic systems required to be installed within limited spaces is driving the demand for smaller power devices, with heights of less than a few dozen meters. Therefore, there is an urgent need for adjustable power devices to meet customers' diverse output requirements, creating a platform-based and systematized approach to low-power devices.

[0003] Existing low-power devices are primarily composed of a bobbin, magnetic core, copper wire, and terminals. Safety regulations require selection and parameter calculation to determine the most suitable core and bobbin, as well as the number of primary and secondary turns and wire diameter. The bobbin production requires a fixed mold, which is molded through high-temperature injection molding and then cooled. The magnetic core is molded in one piece using a fixed-size mold. The copper wire is wrapped around the terminal and wound around the bobbin's central axis. The core and bobbin are then bonded together using a colloid to create the completed low-power device. Existing solutions require the core and bobbin to match in size to facilitate product design and production. However, this can lead to design structures being limited to a single requirement, resulting in cluttered and redundant materials, an inability to achieve systematization, and high production costs. Furthermore, because low-power raw materials are produced through one-piece injection molding, the raw material dimensions cannot be flexibly changed.

[0004] On the other hand, based on market development, the requirements for some specific parameters of products (such as the winding coupling parameters of the product) are higher, but in the existing design of small-power devices, single-slot skeletons are more commonly used, which cannot meet the needs of multiple customers; in order to meet customer performance, it is usually only possible to adjust by changing the winding structure; but there are still limitations, which cannot meet the design requirements to the greatest extent.

It does not necessarily belong to the prior art of this patent application. In the absence of clear evidence that the above content has been disclosed on the filing date of this patent application, the above background technology should not be used to evaluate the novelty and creativity of this application.

In the description of the embodiments of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0033] like Figure 1 As shown, the first embodiment of the present invention discloses a novel adjustable power device, comprising a skeleton 10, a copper wire 20, a terminal 30 and a magnetic core 40, wherein the copper wire 20 is wound on the skeleton 10, the terminal 30 and the magnetic core 40 are respectively fixedly connected to the skeleton 10, and the Figure 2 The skeleton 10 includes a first sub-skeleton 11 and a second sub-skeleton 12 , which are detachably connected so that the length of the copper wire 20 wound on the skeleton 10 can be adjusted.

[0034] Combine Figure 3 The first sub-skeleton 11 is provided with a plurality of first connecting parts 111, and the second sub-skeleton 12 is provided with a plurality of second connecting parts 121. The first connecting parts 111 and the second connecting parts 121 are matched and connected, and the plurality of first connecting parts 111 and the plurality of second connecting parts 121 are respectively extended along the direction in which the first sub-skeleton 11 and the second sub-skeleton 12 are detachably connected, so that the first sub-skeleton 11 and the second sub-skeleton 12 can be spliced to form a skeleton 10 with adjustable length, such as Figure 4 As shown. The number of first connecting portions 111 and second connecting portions 121 is the same, and the spacing between each adjacent first connecting portion 111 is the same as the spacing between each adjacent second connecting portion 121. In this embodiment, the first connecting portion 111 is a buckle, and the second connecting portion 121 is a corresponding slot; in other embodiments, the first connecting portion 111 may be a slot, and the second connecting portion 121 may be a buckle.

[0035] The first sub-skeleton 11 and the second sub-skeleton 12 may adopt a porous silicon carbide ceramic skeleton structure, for example.

[0036] In this embodiment, the skeleton 10 is divided into a first sub-skeleton 11 and a second sub-skeleton 12, wherein the first sub-skeleton 11 and the second sub-skeleton 12 are respectively provided with connecting parts at equal distances along the central axis direction, so that the first sub-skeleton 11 and the second sub-skeleton 12 can be spliced into skeletons 10 of different widths. During use, the user can first adjust the connection state of the first sub-skeleton 11 and the second sub-skeleton 12 through the first connecting part 111 and the second connecting part 121, adjust the overall width of the skeleton 10, and then perform the overall wrapping and winding to complete the physical connection between the copper wire 20 and the skeleton 10, such as Figure 5 Correspondingly, the size of the magnetic core 40 in this embodiment is also adjusted as the size of the bobbin 10 changes.

[0037] In a further embodiment, the copper wire winding portions of the first and second sub-frames 11 and 12 are square in structure, and the magnetic core 40 is also square in structure. By adopting square structures for both the coil axis of the frame 10 and the magnetic core 40, space is fully utilized, reducing the product volume and height.

[0038] In a further embodiment, the novel adjustable power device further comprises at least one blade, with grooves defined in the first sub-frame 11 and / or the second sub-frame 12, into which the blade is inserted and connected. By inserting the blade into the adjustable frame 10, a single-slot frame can be transformed into a two-slot, three-slot, or even multi-slot frame. Multiple groups of copper wires 20 can be placed in different slots, increasing winding options to best meet customer needs and optimize performance.

[0039] In a further embodiment, the terminal 30 includes a first sub-terminal and a second sub-terminal, the first sub-terminal is fixedly connected to the first sub-skeleton 11, and the second sub-terminal is fixedly connected to the second sub-skeleton 12. The combination of the first sub-skeleton 11 and the second sub-skeleton 12 with adjustable spacing allows the spacing between the first sub-terminal and the second sub-terminal to be adjustable. In addition, an adjustable terminal spacing can be designed, where a single terminal is embedded in the front end of the skeleton and connected at the middle end of the skeleton. Based on the design, the appropriate number of terminals is selected for splicing, and the terminal spacing can be adjusted. The length, width, and height of the front-end terminals can also be adjusted based on the safety distance required by the customer. Through this terminal adjustment design, the same design can be used to meet different safety requirements, reducing design work, saving time and costs, and increasing product production consistency.

[0040] In a further embodiment, the novel adjustable power device further includes a housing 50, which is fixedly connected to the magnetic core 40.

By using this coil number adjustment design, a single product can be used to meet a variety of similar market needs, providing users with more options to choose from and reducing design and production costs.

[0042] Similar to Example 1, Example 2 of the present utility model discloses a new type of adjustable power device, including a skeleton 10, a copper wire 20, a terminal 30 and a magnetic core 40, wherein the copper wire 20 is wound on the skeleton 10, and the terminal 30 and the magnetic core 40 are respectively fixedly connected to the skeleton 10, wherein the skeleton 10 includes a first sub-skeleton 11 and a second sub-skeleton 12, and the first sub-skeleton 11 and the second sub-skeleton 12 are detachably connected so that the length of the copper wire 20 wound on the skeleton 10 can be adjusted.

[0043] Combine Figure 6The skeleton 10 in this embodiment includes multiple first sub-skeletons 11, each of which is wound with copper wire 20 of varying densities. A first connecting portion 111 is provided on each first sub-skeleton 11, and a second connecting portion 121 is provided on each second sub-skeleton 12. The first connecting portion 111 and the second connecting portion 121 are matched and connected to each other, so that the second sub-skeleton 12 can be spliced with any one of the multiple first sub-skeletons 11 to form the skeleton 10. In this embodiment, the first connecting portion 111 is a buckle, and the second connecting portion 121 is a corresponding slot. In other embodiments, the first connecting portion 111 can also be a slot, and the second connecting portion 121 can be a buckle.

[0044] In this embodiment, according to different winding methods (such as sparse winding, dense winding, etc.), there will be different types of first sub-skeletons 11 with copper wires 20 wound as assembly parts, and the second sub-skeleton 12 only needs to be spliced with the selected first sub-skeleton 11 through a detachable connection. Through this embodiment, based on different design requirements, the first sub-skeleton 11 with copper wires 20 wound with different numbers of turns can be combined as assembly parts to achieve the output of the same series of products. Through this turn number adjustment design, one product can be used to meet multiple similar market needs, providing users with more options to choose from, reducing design and production costs.

[0045] The new adjustable power device disclosed in Example 1 and Example 2 can, on the one hand, meet the design of user-specific parameters to the greatest extent possible; on the other hand, the design process can meet the flexible size changes of the small-power skeleton, thereby meeting multiple requirements for a single power device, realizing product platformization and systematization, being compatible with various application requirements in the market, and reducing production costs.

[0046] In summary, the new adjustable power device proposed in the present invention can provide users with more and better solution options, save R&D costs and raw material development costs, solve problems such as raw material redundancy, and make the product system platform-based, which is more conducive to market promotion.
